Abstract (en)

[origin: WO0055430A1] The invention concerns a device where creation of mechanical vibration is made with a system (1) of two or more rotating eccentrics (10). Each eccentric (10) is rotated by an individually controlled motor (11) and the angle position of each eccentric (10) is read by an angle sensor (12). With a control and monitoring system (5), the rotation frequency, direction of rotation and phase position of each eccentric (10) can be controlled. By choosing a number of eccentrics, mass of the eccentrics, rotation frequency, direction of rotation and phase position, a force vector diagram of suitable form, in space and time, can be generated. The invention is intended primarily for use in appliances for dynamic compaction of various materials.
